AudioLoopPlayer load

[MikeB]

@d-healey

This is my entry call.
The samples are already all in the pool.

But I still have to load them into the player.
At the moment I do it like this - it works.
Disadvantage. The number of samples in each folder (bass, kick, snare, etc.) must be the same.
The samples are predefined with names in the array.

But in the end I have a different number of samples with different names in the folders.

Engine.loadAudioFilesIntoPool();
var InstrumentID_S1;
var VariationID_S1;
const var Instrument_S1 = ["Bass", "Kick", "Snare", "HiHat", "Tom", "Cymbal", "Crash" ];
const var Sample_S1 = ["sample1.wav","sample2.wav","sample3.wav","sample4.wav","sample5.wav","sample6.wav","sample7.wav", "sample8.wav", "sample9.wav", "sample10.wav", "sample11.wav", "sample12.wav", "sample13.wav", "sample14.wav", "sample15.wav", "sample16.wav", "sample17.wav", "sample18.wav", "sample19.wav", "sample20.wav", "sample21.wav", "sample22.wav", "sample23.wav", "sample24.wav", "sample25.wav", "sample26.wav", "sample27.wav", "sample28.wav", "sample29.wav", "sample30.wav", "sample31.wav", "sample32.wav", "sample33.wav", "sample34.wav", "sample35.wav", "sample36.wav", "sample37.wav", "sample38.wav", "sample39.wav", "sample40.wav", "sample41.wav", "sample42.wav", "sample43.wav", "sample44.wav", "sample45.wav", "sample46.wav", "sample47.wav", "sample48.wav"];

	InstrumentID_S1 = parseInt(value);

@MikeB Change those vars in to reg.

Engine.loadAudioFilesIntoPool() returns an array that contains the names of all of your audio files.

@d-healey

I change WAS in vars reg?????

Engine.loadAudioFilesIntoPool() returns an array that contains the names of all of your audio files.

A little bit more info Dave - you know I'm not on your level :-)

Do a little exploration work:

var myList = Engine.loadAudioFilesIntoPool();
Console.print(trace(myList));

[d.healey]

@Lindon You're just pranking me now with that var. :p

Never use var unless you absolutely have to - paint routines, mouse callbacks, etc. Everywhere else either use const or reg, and if you're in an inline function or callback use local. var should always be your last choice.

--sorry it was just too easy

var AnnoyingDave = true;

Actually tho there is a limit to the number of reg variables you can use I think...

[d.healey]

@Lindon The limit is per namespace. So it's unlikely you'll hit that limit is most instances, if you do, then use var. In our current situation - loadAudioFilesIntoPool - it would make most sense to use a const.

[MikeB]

Ok you two Jedi Knights :-)
So now I have an array with 500 files.

As you can see there are folders - different folders Kick, Snare, etc.
In each folder there are samples with different long names (not like here in the excerpt).
I would like to select the folder (InstrumentID) via one knob and a sample (VariantionID) from this folder via another knob.

 "{PROJECT_FOLDER}Kick/sample1.wav",
  "{PROJECT_FOLDER}Kick/sample10.wav",
  "{PROJECT_FOLDER}Kick/sample11.wav",
  "{PROJECT_FOLDER}Kick/sample12.wav",
  "{PROJECT_FOLDER}Kick/sample13.wav",
  "{PROJECT_FOLDER}Kick/sample14.wav",
  "{PROJECT_FOLDER}Kick/sample15.wav",
  "{PROJECT_FOLDER}Kick/sample16.wav",
  "{PROJECT_FOLDER}Kick/sample17.wav",
  "{PROJECT_FOLDER}Kick/sample18.wav",
  "{PROJECT_FOLDER}Kick/sample19.wav",

@MikeB Everything you need is here - https://docs.hise.audio/scripting/scripting-api/string/index.html :) time to have a problem.

[MikeB]

@d-healey Unfortunately this is of no use to me David - but thanks for your support.

@MikeB

Unfortunately this is of no use to me

Tell me more...

[MikeB]

@d-healey
As I said - this is my starting point
I have two knobs - one calls up the folder (InstrumentID).
the other calls the sample (VariationID)

So at the moment it's like this via the knobs:
a. The folder is selected for example "Kick

b. the sample is selected "sample3.wav".

and this is then loaded into the LoopPlayer.

reg myList = Engine.loadAudioFilesIntoPool();
Console.print(trace(myList));

var InstrumentID_S1;
var VariationID_S1;
const var Instrument_S1 = ["Bass", "Kick", "Snare", "HiHat", "Tom", "Cymbal", "Crash", "Perc", "Electro", "FX" ];
const var Sample_S1 = ["sample1.wav","sample2.wav","sample3.wav","sample4.wav","sample5.wav","sample6.wav","sample7.wav"];



//Start Knob-KitSelector----------------------------------------------------------------------------------------------------------------------
inline function onKitSelector_Knob_S1Control(component, value){
	InstrumentID_S1 = parseInt(value);	
	Synth.getAudioSampleProcessor("Audio Loop Player_S1").setFile("{PROJECT_FOLDER}"+Instrument_S1[InstrumentID_S1]+"/"+Sample_S1[VariationID_S1]); 
};
Content.getComponent("KitSelector_Knob_S1").setControlCallback(onKitSelector_Knob_S1Control);
//End --------------------------------------------------------------------------------------------------------------------------------------

//Start Knob-SampleSelector----------------------------------------------------------------------------------------------------------------------
inline function onSampleSelector_Knob_S1Control(component, value){
	VariationID_S1 = parseInt(value-1);		
   Synth.getAudioSampleProcessor("Audio Loop Player_S1").setFile("{PROJECT_FOLDER}"+Instrument_S1[InstrumentID_S1]+"/"+Sample_S1[VariationID_S1]);   	
};
Content.getComponent("SampleSelector_Knob_S1").setControlCallback(onSampleSelector_Knob_S1Control);
//End --------------------------------------------------------------------------------------------------------------------------------------

Get the list of audio files with Engine.loadAudioFilesIntoPool. Then you can use a loop and the string functions to automatically split that list into two arrays, one for the folders and one for the samples.

[MikeB]

@d-healey Thanks David - that's what I meant - if I could do that I wouldn't ask here.

[d.healey]

@MikeB Which part are you stuck at?

[MikeB]

@d-healey Folders and samples have names of different lengths. How can I separate them with string?
Besides, the user should not get a hi-hat sound if he has selected kick.
But only the samples from the Kick folder.

[d.healey]

@MikeB

If you have a string like const s = "{PROJECT_FOLDER}Kick/sample12.wav"

You can get the folder with const ss = s.substring(s.indexOf("}") + 1, s.indexOf("/"));

Ready for an hour of trial and error ;)

[Natan]

@MikeB Are you going to Include The Audiofiles into Dll?
Or ship With Zip File?

[Natan]

Beaware!

This, Engine.loadAudioFilesIntoPool();
And include Audio Files in resources Will Add Weight to Your Components, Dll, Vst3 Files.
And You easily Will get Out Of Heap error.

[d.healey]

@Natan I think you can ship the audio files as a separate data file.
